Redirect non-www to www or www to non-www - PerfGrid knowledge base

If your application does not handle canonical hostnames, add rules to .htaccess.

All hosts on the directory → force `www`

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{HTTP_HOST} !^www\. [NC]
    RewriteRule ^(.*)$ https://www.%{HTTP_HOST}/$1 [R=301,L]
</IfModule>

Single hostname → force `www`

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{HTTP_HOST} ^example.com$ [NC]
    RewriteRule (.*) https://www.example.com/$1 [R=301,L]
</IfModule>

All hosts on the directory → strip `www`

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
    RewriteRule ^(.*)$ https://%1/$1 [R=301,L]
</IfModule>

Single hostname → strip `www`

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{HTTP_HOST} ^www.example.com$ [NC]
    RewriteRule (.*) https://example.com/$1 [R=301,L]
</IfModule>
